worldsteel represents over 160 steel producers (including 9 of the world's 10 largest steel companies), national and regional steel industry associations, and steel-research institutes. worldsteel members represent around 85% of world steel production.

Membership has increased steadily since worldsteel (formerly the International Iron and Steel Institute (IISI)) was founded in 1967.

Who can become a member?

Steel-producing companies are eligible for either regular or associate membership. Associations, federations and research associations that deal primarily with the steel industry are also eligible for membership. There are three categories of membership:

  • Regular
    Regular members produce at least two million short tons (1.8 million metric tonnes) of crude steel (and equivalent) per annum and operate as independent commercial enterprises. State-controlled companies must be free to make their own economic and investment decisions and operate in a market-based economy. Regular members are entitled to vote at meetings of the Board of Directors.
  • Associate
    Any steel-producing company other than a regular member or a steel-producing company with the potential to become a regular member.                                                                                        
  • Affiliated
    Steel and steel-related industry associations, federations and steel research organisations are eligible to join as affiliated members.

As a member you will be able to:

  • Access the worldsteel extranet, a password protected website available exclusively to members that provides details of all our programmes, activities and campaigns.
  • Benefit from worldsteel’s member-only data, reports, publications, case studies and authoritative works on specialist subjects including the latest technical and economic data on industry trends and performance affecting the global steel industry.
  • Become involved at an international level in common market development programmes and initiatives.
  • Network with other steel industry professionals from around the world at meetings, events and the conferences organised by worldsteel.
  • Join major industry wide working parties, expert groups and committees in worldsteel.
  • Send high-potential employees as Fellows to worldsteel to work on specific projects and gain knowledge of the industry at a global level.

The association exerts no pressure or politics on its members. worldsteel is not involved in competitive issues between steel companies.
